DRIER.

SPECIFICATION forming part of Letters Patent No. 732,451, dated June 30,1903.

Application filed April 13, 1903. Serial no. 152.313. (No model.) i

To all whom, it may concern.-

Be it known that W9,AUGUST ScHoELLHoRN and HERMAN S. ALBRECHT, citizens of the United States, re'sidingin the city of StjLouis, in the State of Missouri, have invented certain new and useful Improvements in Driers, of

which the followingis a full, clear, and exact we to make and which will be durable and simple in its operation and which will elfectually perform its work.

Our invention consists in features of novelty hereinafter fully described, and pointed out in the claim. I V

Figure I is a front view of our improved- Fig. .11 is a rear end view. Fig. III is a horizontal longitudinal section, part broken away, taken on line III IlL-Fig. 1. Fig. IV is a vertical transverse section of the drier. 1

Referring to the drawings, 1 represents a cylinder located in a suitable-furnace 2, by which the necessary heat for drying purposes is produced. The cylinder is provided interiorly with spiral flights 3, which act to turn the niaterial over and keep it stirred up. To each end of the cylinder outside of the furnace is secured a ring or circular rail 4. Each ring rests upon pair of grooved'rollers 5, secured to short shafts 6, that are journaled in boxes 7, mounted on standards 8. The two r'ollers of each pair are placed snfiiciently far apart to allow their .ring 4 to fit down between them, as shown in Fig. I, .the cylinder being thus' supported in a substantial manner. The two shafts 6 on one side of the ma chine are provided with cog-wheels 9, that are engaged by pinions 10 on a drive-shaft 11, provided with a pulley 12. As the' shaft 11 is revolved the cylinder 1 is kept turning,

owing to the friction between the rings 4 and the two rollers 5, the shafts of which are geared to the shaft 11.

At the front end of the cylinder the machine is provided with a feed-funnel 13, held in position by brace-arms 14, and this end of the cylinderhas a head 15 with a central opening to receive the inner end of the funnel 13.

At the other end ofthe machine -the cylinder has an open end and discharges into a spout 16.

We claim as our invent ion v A drier for clay, comprising a furnace, a cylinder open at each end arranged horizontally through the furnace, projecting therefrom at each end, spiral flights within the cylinder, wide rings secured to the projecting ends of the cylinder, a pair of grooved rollers for each ring, shafts supporting opposite rollers on opposite ends of the furnace, standards having journal-boxes for the shafts, spaced from theend walls of the furnace to permit the rollers toebe supported upon the shafts between the furnace end walls and the standards, cog-wheels upon each eudof one of the shafts, a drive-shaft parallel with the rollershaft,pinions on the driveshaft meshing withv the cog-wheels, a funnel atone end of the furnace projecting into the'open end of the cylinder, brace-arms connected with the furnace and the top of the funnel, and an inverted- U-shaped brace connected at its ends to the standards, and supporting the funnel from beneath.
